Isokinetics in Rehabilitation
Isokinetic Exercise Movement that occurs at a constant angular velocity with accommodating resistance
Advantages Maximum muscle tension throughout the range of motion Why? Resistance is variable to match the muscle tension produced at the various points of the range of motion. Isokinetic machines allow the angular velocity to be preset and accommodate the resistance
Advantage cont. Ability to work at various velocities to simulate functional activity But: functional activity usually greatly exceed the velocity capacity of isokinetic dynamometers (e.g. pitchers 6,500-7,200 degrees/sec., machine 300-500 d/s) Testing usually non-weight-bearing; not representative of functional activities
